Check-Return Valve – Reliable Protection and Flow Control

The check-return valve ZGLO Fig. 215C is a versatile device combining the functions of a check valve and a shut-off valve. It provides effective protection against backflow of the medium while simultaneously enabling complete flow shutoff when required. The valve’s design allows for precise control of the medium within the system, making it an ideal solution for a wide range of industrial applications and sanitary installations.

This valve stands out for its robust construction and high manufacturing quality. The body, made of ductile iron, ensures strength and corrosion resistance, while internal components – stem, mushroom, and body ring – are manufactured from stainless steel, guaranteeing long-term reliability even under demanding operating conditions. The 31-type construction, featuring a floating mushroom with spring, ensures smooth operation and minimizes the risk of mechanical damage.

Construction and Applications

The check-return valve Fig. 215C is suitable for use in a broad range of systems, including:

• Water supply and sewage systems,
• Heating and cooling installations,
• Chemical and petrochemical industries,
• Power generation.

Thanks to flanged connections (both connections – 1 and 2), installation is simple and fast, resulting in time and cost savings. The cylindrical stem extension facilitates valve maintenance and enables precise control of medium flow.

Key Product Features:

• Versatility: Combines check valve and shut-off valve functions in a single unit.
• Durability: Ductile iron body ensures resistance to high pressure (PN 25) and corrosion.
• Reliability: Stainless steel internal components guarantee long-term, failure-free operation.
• Easy Installation: Flanged connections simplify and accelerate installation.
• Precise Control: Enables complete shutoff of medium flow.
• Design: Floating mushroom with spring minimizes risk of mechanical damage during operation.
• Wide Application Range: Ideal for various media and operating conditions in industrial and sanitary systems.

This valve is particularly recommended for applications requiring both protection against backflow and the ability to manually close the circuit. Its robust construction and high-quality materials ensure long-term, maintenance-free operation, resulting in reduced operating costs and increased system efficiency.
